TOOL-HANDLE FAS'LENING.

To @ZZ @lf/1.0m 'it 'may concern.'

lle it knovrn that l, Tincononn (l. Sinnamon, a citizen of the United States, residing at Chicago, in the county et Cook and State o1 illinois, have invented certain nevv and useful improvements in Tool-lilandle Fastenings, of which the it'olleiving is a specilcation.

This invention relates. to fastenings Jfor retaining` tools in socket-handles, and itsV object is to provide a novel and improved tastening whereby the tool will be securely held in the socket.

The herein stated object is attained by means ot a combination and arrangement of parts to be hereinafter described and claimed, and in order that the invention may be better miderstood, reference is had to 'the accompanying drawing, in Which- Figure 1 is an elevation of the tool and its handle; l? EZ is a longitudinal section on the line 2-2 oit Fig. 1; Fig. 3 is an end vien7 of the handle-socket, and Fig. al is a cross-section on the line ,lA-'w1 of Fig. 1,

Reife ng specifically to the drawing, 5 denotes a chisel or other tool which is to be secured in a handle-socket G. The shank of the tool has a base portion 7 from which eX- tends a tang 8, the outer end of which is ref duced or stepped to semicircular form, as indicated at 9. The wall of the socket at that end into 'which the tang is inserted is thickened, as indicated at 10, and formed with a shoulder 11, against which the shoulder formed by the base 7 squarely abuts, and the side of the base is beveled, as indicated at 12, to produce a taper! In front oit' the shoulder 11 the socket is `liared, the Tvall thereof being beveled on the inside to correspond to the bevel 12. Thus, the base portion of the shank fits snugly in the socket, but it is prevented from being tightly Nedved therein by the shoulder 11.

The Wall or' the socket is internally screw-threaded to receive and hold a sleeve 13, the saine being iiush at one end With the shoulder 11.v and abutting against the base portion 7 of the toolshanlt. The inside di- Specification of Letters atent.

ameter of this sleeve is such that the tang 8 may be insertedY thereinto with a snug lit. The rear end of the sleeve has an opening 14 corresponding1 in shape to the reduced portion 9 oi the tang, the saine seating in the opening, .vhereby the tang is held against rotary motion in the sleeve.

Behind the part 10 the sleeve 13 is spaced from the wall of the socket and carries a `flat spring secured at one end to the outside ot the sleeve, as indicated at 16. The spring extends in a curve partly around the sleeve, and carries at its free end a segmental llatch 17 slidably mounted in a cross slot 18 in the sleeve and adapted to be seated in a transverse groove 19 in the tang 8. '1 he latch has a stem 20 to which the tree end of the spring is made ifa st, and said stem screvvs into a knob or `linger-piece 21 seating in a transverse slot 22 in the wall of the socket. The latch is beveled to snap into the groove 19. The spring 15 holds the latch 17 seated in the groove 19, and with the latch in this position the tang 8 is securely locked against longitudinal movement in the sleeve 13. To release the tang, the knob 21 is pressed side- Wise toward one end oi the slot 22, Whereupon the latch rises out o1'l the groove 19, as shown by dotted lines in Fig. 4, and when it clears the tang, the tool may be removed. There is sutlieient space in the socket to ac` commodate the spring. The sleeve 13 is mounted in place by being inserted into the socket 'from the rear end thereof, the opening 14 affording a hold for a screw-driver for screwing the sleeve into place.

1 claim:

rllhe combination with a handle-socket having a cross slot; of a tool having a tang provided with a transverse groove, a sleeve mounted in the handle-socket and receiving the grooved portion of the tang, said sleeve having aportion which is spaced from the Wall of the socket and provided with a cross slot registering with the first-mentioned cross slot and the groove of the tang, means for holding the tang against rotary movement in the sleeve, a latch slidable in the cross slot of the sleeve and engageable with the transverse groove of the tang, a lingerpece attached to the latch and passing through the cross slot of the handle-socket to the outside of the latter, and a spring made fast at one end to that portion of the sleeve which s spaced from the Wall of the handle-socket, said spring encircling the sleeve externally and having its free cud connected to the latch. 10
